Serial No. 409,455.

modified form, a portion thereof being Be it known that I, JOAQUIN FERRERES, a broken away.

citizen of the Republic of Cuba, and a resident of Habanai Cuba, have invented a new and Improved Calendar, of which the following is a full, clear, and exact description.

This invention relates to certain improvements in calendars, and more particularly to that type of calendar in which there are provided two members rotatably mounted in respect to each other, one of said members bearing the names of the days of the week and the other of said members bearing the numerals of the days of the month, said names and numerals being so arranged that by the movement of one member in respect to the other, the name of any day of the week may be brought into registry with any numeral of the month. This type of calendar is commonly so constructed that the i'novement of one member in respect to the other, serves to bring to view through a suitable aperture, the names of the days of the month, and when the name of any particular month of a given year is exposed, the names oft-he days of the week will be in registry with the numerals of the corresponding days of the month for that particular month.

The object of my invention is to so construct the members that the names of the days of the week and the numerals of the days of the month will be right-side up and easily read, irrespective of the extent to which the rotary member is rotated. To accomplish this object, I provide a rotary member with a plurality of concentric rows of the successive days of the week, the rows being substantially identical, save that the names of the days of the week are right side up to the observer at a different portion of the arc of a circle for each row, and the other member is so constructed as to conceal all portions of each row, except that portion in which the names are always right side up.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the ligures, and in which Figure 1 is a face View of a calendar constructed in accordance with my invention; Fig. 2 is a transverse section on the line 22 of Fig. 1; Fig. 3 is a face view of the rotary member; and Fig. 4 is a face view of a bers, one a stationary other a rotary member In the spcc'iic form of my invention illustrated in 1, 2 and 3, I. provide two memn'iember 10 and the 11 pivoted thereto by any suitable form of pivot 12. The rotary member 11 is provided with three concentric rows of the names of the days of the week. The rows are substantially identical in all respects, save the angle at which the names may be best read; that is, the name of any particular day of the week in one row is in the same radial line as the name of the same day of the week in the other rows. In the innermost row, each name is printed circumferentially of the row, whereby at the upper portion 13 of the row, each name appears right side up and easily read, while the bottom portion 13 the words appear wrong side up, and at the right and left-hand portions 13 and 13, the words extend substantially vertically. Thus, itwill be noted, that the only portion of this row which can be read by an observer is the uppermost or top portion 13. In the second or middle row, the words are printed radially and most easily read at the right hand portion of the row. In this portion 14., the words appear right side up, while at the diametrically opposite portion 14?, the words are wrong side up and not easily read. At the uppermost portion 14, and at the lowermost portion 145 the words appear vertically and not easily read. In the outermost row, the words are also printed radially but each word is bottom side up in respect to the adjacent word of the middle row above described. In the outermost row, the words in the lefthand portion 15 are right side up, while the words in the right-hand portion 15 are wrong side up, and the words in the uppermost portion 15 and in the lowermost portion 15" are arranged substantially vertically.

The stationary member is provided with three slots or openings, each forming a portion of the arc of a circle, the three portions being in different arcs of concentric circles. Through one slot 16, only the uppermost portion 13 of the inner row is visible; through another slot 17, only the right-hand portion 14 of the middle row is visible, while through the third slot 18, only the left-hand portion of the outermost row is visible. The stationary member bears the numerals of the days of the month arranged in a substantially annular row 19, adjacent said slots, and each numeral is so arranged that it appears right slde up. The stationary member is also provided with a slot 20, and the rotary member carries an annular row 21, bearing the names of the months of the year, any one of which may be brought to view through the slot 20. For a given year, when any particular month of the row 21 is visible through the slot 20, the proper day oI the week will be in registry with the proper numeral of the month, and each and every name of the days of the week which is visible through the several slots, will be read.

In the form illustrated in Fig. 4, the rotary member 11 instead of bearing three concentric rows of numerals, is provided with only two, and the stationary member 10 is provided with one slot 22, through which the lower half of the outer row may be seen, and provided with two slots 23 and 23*, through which most of the upper portion of the inner row of names may be seen. The two rows correspond to the outermost and the middle rows of the form illustrated in Figs. 1 to 3, inclusive, and the visible names of the days of the week register with the numerals of the days of the month printed on the stationary member. In this form, as in the other, all names of the days of the week which are visible are in substantially an upright position and easily read. 'In this form, the opening 20 through which the name of the particular month may be seen, is provided with a small auxiliary opening 20, through which the number of days in the particular month is disclosed. This number and the auxiliary opening serve to insure the rotation of the rotatable member to the correct position.

i I l I right side up and easily Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:

1. A calendar, comprising two relatively movable members, one of said members having a plurality of concentric rows of the days of the week, the names in each row appearing right side up in a different sector thereof, and the other of said members serving to conceal each row save the sector thereof in which said names appear right side up.

2. A calendar, comprising two relatively movable members, one of said members having a plurality of concentric rows of the days of the week, the names in each row appearing right side up in a different sector thereof, and the other of said members having a plurality of slots or openings through which the names appearing right side up are visible and also having the numerals of the days of the month disposed adjacent said slots or openings and arranged to register with said names, and one of said members having a row of the months of the year and the other of said members having an opening through which any one of said months may be brought to view, the numerals of the months and the days of the week being in proper registry for any particular month, when the name of that month is visible through said last-mentioned openin In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
